[0027] The technical solutions in the embodiments (or, the implementation manners) of the application will be described clearly and completely in conjunction with the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated.

[0028] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0029] The carbon brush replacement device according to embodiments of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can complement or combine with each other.

[0030] This application provides a carbon brush replacement device, such as... Figure 1 As shown, the carbon brush replacement device includes a first handle 10, a second handle 20, and a pusher 30. The first handle 10 has a first clamping portion 11 at its end. The second handle 20 has a second clamping portion 21 at its end and is connected to the first handle 10 via a first connection point A. The first handle 10 can rotate around the first connection point A, causing the first clamping portion 11 to move closer to and further away from the second clamping portion 21. The first clamping portion 11 and the second clamping portion 21 cooperate to form a clamping space for accommodating the carbon brush. The pusher 30 is slidably connected to either the first handle 10 or the second handle 20, and the pusher 30 slides relative to either the first handle 10 or the second handle 20, causing its end to extend into and out of the clamping space.

[0031] In DC motors, carbon brushes are typically fixed to the brush holder using spring plates. The spring plates apply a certain pressure to the carbon brushes to ensure close contact between the carbon brushes and the motor's commutator or slip rings.

[0032] When replacing the carbon brushes of a DC motor using a carbon brush replacement device, the second clamping part 21 of the carbon brush replacement device is inserted into the brush holder and contacts the carbon brush and spring plate. The first handle 10 moves the first clamping part 11 closer to the second clamping part 21, compressing the spring plate and clamping the carbon brush and spring plate within the clamping space. At this point, the carbon brush and spring plate can be removed from the brush holder by dragging the carbon brush replacement device. Then, the first clamping part 11 and the second clamping part 21 are used to clamp the replaced carbon brush and spring plate, aligning them with their mounting positions on the brush holder. Finally, the end of the pushing member 30 is pushed into the clamping space, pushing the replaced carbon brush and spring plate onto the brush holder, completing the carbon brush replacement.

[0033] The carbon brush replacing device can position, clamp and move the carbon brush and the spring sheet more quickly, is simple and convenient to operate, can greatly shorten the time required for replacing the carbon brush, can effectively improve the overall operation efficiency of the equipment, and can reduce the production stagnation loss caused by replacing the carbon brush, especially in the scene of industrial production and the like which is strict with the equipment downtime.

[0034] In one embodiment, the first clamping part 11 comprises a first bottom plate 111 and a first side plate 112, the first bottom plate 111 is connected with the end of the first handle 10, and the first side plate 112 is connected with the first bottom plate 111. The second clamping part 21 comprises a second bottom plate 211 and a second side plate 212, the second bottom plate 211 is connected with the end of the second handle 20, and the second side plate 212 is connected with the second bottom plate 211. When the first clamping part 11 cooperates with the second clamping part 21 to form the clamping space, the first bottom plate 111 is arranged opposite to the second bottom plate 211, and the first side plate 112 is arranged opposite to the second side plate 212.

[0035] The first bottom plate 111 and the second bottom plate can provide a stable support plane for the carbon brush. When the carbon brush and the spring sheet are located in the clamping space, the first bottom plate 111 and the second bottom plate 211 can constrain the carbon brush and the spring sheet, so that the carbon brush and the spring sheet remain stable. The spring sheet usually has a certain elasticity and shape, and is prone to deformation or displacement during clamping. The first side plate 112 and the second side plate 212 can provide good lateral constraint for the spring sheet, so that the spring sheet can be accurately located at a predetermined position in the clamping space and maintain a correct relative positional relationship with the carbon brush, which is beneficial to improve the installation convenience and accuracy.

[0036] Figure 2 And Figure 3 In the embodiment shown, one side of the first bottom plate 111 is provided with the first side plate 112, and one side of the second bottom plate 211 is provided with the second side plate 212. In other embodiments, two first side plates 112 can be respectively arranged on both sides of the first bottom plate 111, and two second side plates 212 can be respectively arranged on both sides of the second bottom plate 211. When the first clamping part 11 cooperates with the second clamping part 21 to form the clamping space, the two first side plates 112 can be located between the two second side plates 212, or the two second side plates 212 are located between the two first side plates 112, or the two first side plates 112 respectively away from the end of the first bottom plate 111 abut with the end of the second side plate 212 away from the second bottom plate 211.

[0037] In one embodiment, as Figure 1 And Figure 4As shown, the pushing member 30 comprises a pushing rod 31 and a pushing part 32. The pushing rod 31 is slidable relative to the first handle 10 or the second handle 20. The pushing part 32 comprises a connecting plate 321 and two oppositely arranged pushing arms 322. The connecting plate 321 is connected with the end of the pushing rod 31, and the pushing arms 322 are connected with the side of the connecting plate 321, and extend away from the pushing rod 31.

[0038] During the installation of the spring sheet and the carbon brush, the pushing rod 31 transmits a pushing force to the connecting plate 321 and the pushing arms 322, and the connecting plate 321 can abut against the spring sheet and the carbon brush and push them out of the clamping space. The two pushing arms 322 can effectively prevent the carbon brush and the spring sheet from tilting due to uneven force during pushing, and ensure that the carbon brush and the spring sheet can smoothly and accurately enter the installation position of the brush holder.

[0039] In an embodiment, as shown in Figure 1 and Figure 3 The first handle 10 or the second handle 20 is provided with a slide 22, the axis of the slide 22 passes through the clamping space, and the pushing rod 31 is located in the slide 22 and is slidable along the slide 22. The slide 22 can guide the sliding of the pushing rod 31 and limit the excessive degrees of freedom of the pushing rod 31 in other directions, avoiding unnecessary shaking, rotation, etc. of the pushing rod 31 during operation, and ensuring the stability and reliability of the entire carbon brush replacement operation.

[0040] In an embodiment, as shown in Figure 1 and Figure 3 The slide 22 comprises a first sub-slide 221 and a second sub-slide 222. The second sub-slide 222 is located at the end of the second handle 20 away from the second clamping part 21, and the first sub-slide 221 is located between the second clamping part 21 and the second sub-slide 222. The pushing part 32 is located between the first sub-slide 221 and the second clamping part 21, and the pushing rod 31 passes through the first sub-slide 221 and the second sub-slide 222. The first sub-slide 221 and the second sub-slide 222 can further limit the degrees of freedom of the pushing rod 31 in multiple directions, and compared with a single slide, can more effectively prevent the pushing rod from swinging, deviating, and unnecessary rotation, etc. abnormal movement, so that the pushing part 32 can smoothly push the carbon brush and the spring sheet.

[0041] In other embodiments, the slide can also be provided on the first handle 10, the second sub-slide is located at the end of the first handle 10 away from the first clamping part 11, the first sub-slide is located between the first clamping part 11 and the second sub-slide, and the pushing part is located between the first sub-slide and the first clamping part.

[0042] In one embodiment, such as Figure 1 As shown, the first handle 10 includes a first handle portion 101 and a second handle portion 102. One end of the first handle portion 101 is connected to the first clamping portion 11, and the other end is connected to the second handle 20 via the first connection point A. The end of the first handle portion 101 away from the first clamping portion 11 is also connected to the second handle portion 102 via the second connection point B. The carbon brush replacement device also includes a connecting rod 40, one end of which is connected to the second handle portion 102 via the third connection point C, and the other end is connected to the second handle 20 via the fourth connection point D. The third connection point C is located on the side of the second connection point B away from the first handle portion 101. The fourth connection point D is located on the side of the first connection point A away from the second clamping portion 21.

[0043] When clamping the carbon brush and spring sheet, press down on the end of the second handle 102 away from the first handle 101, causing the second handle 102 to rotate around the second connection point B toward the second handle 20. This causes the end of the connecting rod 40 connected to the second handle 102 to rotate around the fourth connection point D, gradually increasing the angle between the portion of the second handle 102 located between the second connection point B and the third connection point C and the connecting rod 40. During this process, the fourth connection point D remains stationary, the third connection point C moves toward the second clamping part 21, and the second connection point B rotates around the first connection point A. This allows the first clamping part 11 of the first handle 101 to rotate around the first connection point A, thereby reducing the angle between the first clamping part 11 and the second clamping part 21, thus clamping the carbon brush and spring sheet within the clamping space.

[0044] When the second connection point B, the third connection point C, and the fourth connection point D are aligned in a straight line, the first handle 101, the second handle 102, and the connecting rod 40 form a self-locking mechanism. At this time, even if the operator no longer applies pressure to the first handle 10 and the second handle 20, the first clamping part 11 and the second clamping part 21 can stably maintain the clamping state of the carbon brush and the spring sheet, effectively preventing the carbon brush and the spring sheet from accidentally falling off during transfer or further operation, thus ensuring the stability and safety of the operation.

[0045] In one embodiment, such as Figure 1 As shown, the carbon brush replacement device also includes an elastic element 50. One end of the elastic element 50 is connected to the first handle 101 through a fifth connection point E, and the other end is connected to the second handle 20 through a sixth connection point F. The fifth connection point E is located between the first connection point A and the second connection point B, and the sixth connection point F is located between the first connection point A and the fourth connection point D.

[0046] The elastic member 50 can store and release energy by its elastic deformation. After the operator completes the replacement of the carbon brush and the spring sheet by using the carbon brush replacement device, the elastic member 50 can make the first handle 10 and the second handle 20 return to the initial position, realize the function of automatic reset, make the carbon brush replacement device can quickly prepare for the next carbon brush replacement operation, improve the convenience and continuity of the use of the entire device, and make the operation more labor-saving and convenient.

[0047] In Figure 1 In the embodiment shown, the elastic member 50 is a spring, and in other embodiments, it can also be an elastic rubber belt, etc.

[0048] In one embodiment, as Figure 1 shown, the second handle 20 further comprises an adjusting member 23, which is arranged at the end of the second handle 20 away from the second clamping part 21 and abuts against the end of the connecting rod 40. The adjusting member 23 is used to adjust the distance between the end of the connecting rod 40 connected with the second handle 20 and the second clamping part 21.

[0049] When the distance between the end of the connecting rod 40 connected with the second handle 20 and the second clamping part 21 decreases, the connecting rod 40 pushes the second handle part 102 to move away from the second handle 20, drives the first clamping part 11 of the first handle part 101 to rotate around the first connecting point A towards the second clamping part 21, thereby reducing the included angle between the first clamping part 11 and the second clamping part 21; when the distance between the end of the connecting rod 40 connected with the second handle 20 and the second clamping part 21 increases, the elastic member 50 contracts, drives the fifth connecting point E to rotate around the first connecting point A, and increases the distance between the first clamping part 11 and the second clamping part 21. Through the above arrangement, the included angle of the first handle 10 and the second handle 20 at the initial position can be adjusted, and it is ensured that the carbon brush replacement device can clamp and replace carbon brushes of different sizes.

[0050] In Figure 1 the embodiment shown, the adjusting member 23 is an adjusting screw, one end of the adjusting screw extends into the end of the second handle 20 away from the second clamping part 21 and abuts against the end of the connecting rod 40. The contact point of the connecting rod 40 with the adjusting screw is the fourth connecting point D. By rotating the adjusting screw, the distance between the fourth connecting point D and the first connecting point A can be adjusted, and the included angle between the first clamping part 11 and the second clamping part 21 is adjusted.

[0051] In one embodiment, as ​As shown, the carbon brush replacing device further comprises an unlocking handle 60, one end of the unlocking handle 60 is connected with the second handle part 102 through a seventh connecting point G, the seventh connecting point G is located on the side of the third connecting point C away from the second connecting point B, and the other end of the unlocking handle 60 is rotatable about the seventh connecting point G.

[0052] When the first handle part 101, the second handle part 102 and the connecting rod 40 form the self-locking state, an external force is needed to remove the self-locking state, by pressing the end of the unlocking handle 60 away from the first clamping part 11, the second handle part 102 can be pried at the seventh connecting point G, so that the second handle part 102 rotates about the second connecting point B away from the second handle 20, and then the self-locking state of the first handle part 101, the second handle part 102 and the connecting rod 40 is removed. In this way, the operator can contact the self-locking state with one hand in a holding manner, so that the operation process is more smooth.

[0053] In one embodiment, when the first handle 10 comprises the first handle part 101 and the second handle part 102, the pushing piece 30 is connected with the second handle 20. In this way, the carbon brush replacing device has a compact structure and reasonable layout, and the pushing piece 30 can avoid interfering with the first handle part 101 or the second handle part 102, so as to ensure the smoothness of the operation of the carbon brush replacing device.

[0054] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of the present application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
